Application filed January 11!, 1913. Serial No. 741,424.

To all whom it may concern:

Be it known that I, SHERMAN G. BERRY, a citizen of the United States,and a resident of Tyndall, in the county of Bonhomme and State of SouthDakota, have invented a new and Improved Starter for InternaLCombustionEngines, of which the following is a full, clear, and exact description.

My invention relates to a starting construction for internal combustionengines, and the object thereof is to provide a starter comprising apipe connected to supply air avarmed by the exhaust of the engine to thecarbureter, and having means therein for vaporizing. a sufficientquantity of gasolene independently of the carburetor in ordertofacilitate the starting of the engine in very cold weather.

Reference is to behad to the accompanying drawings forming a part ofthis spccifi cation, in which the same characters of reference indicatethe same parts in all the views.

Figure 1 shows an end view, partly in section, of an internal combustionengine having my invention applied thereto; Fig. 2 is a view on the line2-2 of Fig. 3, showing the warm air pipe carrying my starting device inlongitudinal section; and Fig. 3 is a cross-sectional view on the line3--3 of Fig. 2.

Referring to the drawings the numeral 1 indicates an internal combustionengine of any well-known type having a supply pipe 2 leading to thefiring chamber from the carburetor 3. This carburetor is connected by apipe 4 with a jacket 5 which may surround the exhaust pipe, this jacketof course communicating with the atmosphere so as to supply warm air tothe carburetor when the engine is in operation.

In the pipe 4 is a valve or damper 6 connected to an arm 7 by means ofwhich the valve is opened, and also connected to a spring 8, whichnormally acts to hold this valve in position to shut the pipe 4. Betweenthis valve and the carbureter the pipe 4 is provided with a projection 9having one end open and screw-threaded on its outside near the endthereof to receive a flanged ring 10, this flanged ring serving tosecure a sheet of gauze over the end of the projection 9. Thisprojection is likewise closed by means of a sheet of gauze 12, andbetween the gauze 11 and 12 is a body of porous ma erial for a purposewhich will appear later. Between the projection and the carbureter thepipe 4 has an opening 14 over which is placed a sheet of gauze 15.Surrounding the pipe at this point is a sleeve 16 having an opening 17which can be made to register with the opening 14. This sleeve isadjusted by means of a fingerhold 18 and rests upon a flange or collar19 to prevent the dislocation of the sleeve 16. The upper end of thepipe 4: may have a sheet of gauze 20 to prevent the entrance of foreignsubstances from the jacket 5.

In operation the valve 6 is normally open so as to permit warm air topass freely to the carbureter 3, but when the engine is to be startedthe arm 7 is released by means of a suitable link or lever connectedthereto, and the spring 8 allowed to close the valve 6, The absorbentmaterial 13 is now saturated with a su'lii'cient quantity of g'a'soleneby pouring the same in through the gauze 11. The opening 14 must heclosed and then the engine can be cranked. This causes air to be drawnin through the porous material 13 and through the carburetor to thesupply pipe 2, from whence it passes into the firing chamber, providinga sufficiently rich mixture for ready combustion. As soon as the engineis running the valve 6 is opened and the fuel is supplied to thecarburetor in the regular way. Of course in warm weather when there isno need for supplying warm air to the carbureter the velvet can beclosed and air supplied through the opening 14. Furthermore, if at anytime it is desired to clean the cylinder of the engine of carbon, thiscan be done by closing the valve 6 and pouring kerosene on the porousmaterial 13. This oil will be carried into the cylinder and effectuallyremove any deposits on the inside of the same. My starter therefore notonly facilitates setting the engine in operation by more readilyvaporizing gasolene than can be done with an ordinary carbureter, but itmakes it easier to clean the engine whenever cleaning is necessary.

I wish to have it understood that the above description is illustrativeonly, disclosing but one embodiment of my invention, and I do not careto be limited to the exact details shown and described, but reserve tomyself the right to make whatever changes in the shape, size andarrangement of the parts as fairly fall within the scope and spirit ofmy invention.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent:

1. In a starting device, the combination of a conduit adapted to beconnected with the firing chamber of an internal combustion engine, saidconduit having a valve for controlling the admission of air thereto a dprovided with a lateral opening, and a hflder for absorbent materialsecured to the ciinduit over the opening thereof, the absorbent materialbeing adapted to receive hydrocarbon to be vaporized by air passingthrough the absorbent material into the conduit.

2. In a starting device, the combination of a conduit, .means forconnecting said valve-controlled conduit to the firing cham-.

ber of an internal combustion engine, said conduit having an open-endedboss projecting laterally therefrom, and means for in closing a mass ofabsorbent material in said boss to receive hydrocarbon to be vaporizedby air passing through said boss into the conduit and thence to thefiring chamber.

3. In a starting device, the combination of a conduit, means forconnecting said conduit to the firing chamber of an internal combustionengine, means for supplying warm air to said conduit, a valve forshutting off said warm air supply, another valve for supplyingatmospheric air to said menses conduit when the warm air supply is notneeded, and means carried. by the conduit between the valves forreceiving hydrocarbon to be vaporized by air passing through the sameinto the conduit.

4. In a starter, the combination of a con- 7 duit, means for supplyingwarm air to said conduit at one end, means for connecting the other endof said conduit to the firing chamber of an internal combustion engiige, a Valve in said conduit for shutting off said warm air supply, alateral hollow boss projecting from said conduit beyond said valve,means for inclosing a mass of absorbent material in said hollow boss toreceive hydrocarbon to be vaporized by air passing into the conduit whenthe said valve is closed, said conduit having an opening beyond theboss, and a movable sleeve surrounding said conduit and having anopening therein to uncover or close the opening in the conduit, for thepurpose set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.
